ARGYLE, Texas -

Parts of North Texas spent Monday cleaning up after strong winds and hail caused major damage late Sunday.

The huge hailstones pounded homes and windshields in parts of Collin and Denton counties Sunday night, including the windshield on a FOX 4 photographer’s truck.

Hail damage took most of Little Elm ISD’s school buses out of commission. A total of 35 of the district’s 48 buses were damaged by the storms. The district borrowed buses from neighboring districts to get kids to school Monday morning. They ran two and a half hours later than usual.

A business owner in Bartonville showed FOX4 that nine of his employees’ vehicles were smashed out.

“It was, I mean it sounded like machine gun fire but it was just nonstop, you know, tennis ball to racquetball size hail coming down for 15 minutes,” said Corey McKanna. "Right now we're just focusing on getting everybody's vehicles up and running, so they are safe to drive.”

The National Weather Service determined the damage in the Denton County city of Justin was not from a tornado, but was 75-85 MPH straight-line winds. One viewer there shared video of strong winds toppling a pergola in his backyard.

The Insurance Council of Texas said thousands of homeowner and auto claims have already been filed, but it will be a few days before there is an estimate for the total insured dollar loss.
